Summary, etc. |
<p class="Abstract" style="text-align: justify;">The recalcitrant nature of black gram is the major constraint of <em>in vitro </em>regeneration and <em>agrobacterium-</em> mediated genetic transformation, to overcome this, a productive shoot regeneration protocol has been achieved in black gram cultivar T9 using 7-day old cotyledonary node explants excised from <em>in vitro-</em> raised black gram seedlings using meta-topolin. An aromatic cytokinin,meta-topolin along with BA (1.5+0.5 mg/L) in 0.50 strength MS medium with 1.5% (w/v) sucrose exhibited a maximum number of multiple shoots (32.0±0.37 shoots/explant) at the end of 6 weeks of culture. The shoots were elongated in (6.40±0.50 cm/shoot) in MS medium supplemented with GA<sub>3</sub> (2.0 mg/L). A maximum number of roots (9.60±0.50/shoot) and root length (11.20±0.73 cm/shoot) were obtained in combination with β-cyclodextrin(a cyclic oligosaccharide;1.5 mg/L) and IBA (1.5 mg/L). The rooted plantlets were hardened and acclimatized with least mortality rate of 2% in pot mixture consisting red soil:sand:farm yard manure (FYM) (2:1:1) and grown in green house with 85% relative humidity. Ploidy levels were analyzed using flow cytometry which confessed the chromosomal stability in <em>invitro</em> raised plants similar to parent plants. This protocol may be useful for producing transgenic black gram with desirable agro-traits in Indian cultivars.</p> |
